_clear_when_taken takes the operator's arm notice down the moment the
controller takes the press (the button lights for the arm wait and
goes out at the press). Its watch thread polled the button LEDs every
50 ms with the arm's timeouts as its only exits: 30 minutes for the
button to light, 90 minutes in all. Nothing in it read the run's end,
the abort event, or whether the notice it guarded still stood, so a
test that ended before the press (a FAIL on the way to the arm) left a
thread reading up to six sysfs files twenty times a second behind it.
The watch now lives only as long as the notice it guards and the run:
a notice cleared or replaced, a run that finished, or an abort ends
it. `standing()` reads both under the run's lock on every poll, and
the poll waits on the run's abort event instead of sleeping, so an
abort ends the wait at once. The cadence stays 50 ms: the notice still
drops within 50 ms of the press. The watch commands nothing; no press,
judge, or energy path changes.
Proof: forgetest-ci "Unit tests" (`python -B -m unittest discover -s
tests -v` in forgetest), on Ubuntu 24.04 with python 3.12:
test_fixture.py's test_the_arm_notice_comes_down_when_the_press_is_taken
gains the leg that a run finished before the press ends the watch
within 2 s and leaves the finished run's notice as it was; the file's
21 tests pass; test_setup_burns.py, whose burns reach the watch
through press_now, passes its 19 tests and leaves no
forgetest-arm-notice thread behind (10 before this change); and
test_server.py, test_operator.py and test_queue.py pass. Negative control on a scratch
copy: the new leg against the unchanged runner fails with the
forgetest-arm-notice thread still alive after the run finished.
pyflakes reports no undefined name.
Acceptance: every catalog test's fingerprint moves: runner.py is a
shared judge, in every implementation hash (43 of 43 move). Against
the campaign this series already needs, that adds no run: 850498f
moved all 43 once. tests/ are in none.

"""The bench actuator as the tool sees it.
|
|
|
|
The fixture is a box on the network that opens the lid loop, pulls the
|
|
interlock loop and presses the button on request. What has to hold: the
|
|
tool speaks its API under the key, falls back to the operator when it
|
|
cannot act, moves an operator test it can perform alone into the
|
|
unattended queue (never a live one, never one that needs a person for
|
|
anything else), refuses a prompt during such a run rather than hanging on
|
|
it, releases what the box still holds after every run, and presses the
|
|
arm button only where the bench opted in.
